C2MS11 — Add field for USER to Message Header

In Log, Directive Request, and Simple Service Request, there is a USER field for use by communicating applications. This field should be moved to the Message Header, so that any message can utilize this field.

Note: in the Log Message this field is used in the subject, so is defined as a Header String. In the Directive and Simple Service messages, it is not used in the subject so is defined as a string.

Note 2: There is another field in the Message Header called USER-NAME; this is a tracking Field, so is reserved for use by the implementation and is the account/user name that started the application.
